To a/ZZ whom t may concern,.-

Be it known that I, LEWIS W. MOZINGO, a citizen of the United States,residing at Westport, in the county of Jackson and State of Missouri,have invented a new and useful Gistern-VVater Filter, of which thefollowing is a specification.

My invention relates to a water-filter particularly adapted for use inconnection with cisterns which are supplied by rain, and the objects inView are to provide a simple and efficient construction whereby thefiltering and refuse chambers are automatically iiushed after thecessation of the supply, to provide improved means for closing theoutlet from the waste or refuse chamber during the supply of water tothe lter, and, furthermore, to provide means whereby all of the parts ofthe Iilter are detachable to give access to the interior thereof tofacilitate cleaning.

Further objects and advantages of the invention will appear in thefollowing description, and the novel features thereof` will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a vertical central section of a filterconstructed in accordance with my invention, the valve which controlsthe waste pipe or outlet being elevated. Fig. 2 is a similar viewshowing the wastepipe controlling-valve closed. Fig. 3 is a View of theperforated shield for protecting the bucket. Fig. 4 is a transversehorizontal section on the line 4 4 of Fig. 1 to show the spider forsupporting the lower end of the spring which elevates the bucket whenrelieved of weight.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawings. l

1 designates the main receptacle of the l ter, which may be cylindricalin construction, as shown in the drawings, the same being provided withan inverted conical bottom 2 and a removable top 3, said top beingprovided at its center with an opening 4, having a depending annular lip5, which fits Within the upper end of a vertical conductor 6, arrangedaxially in the main receptacle and attached at its lower end to the apexof a conical perforated partition 7. The conical partition 7 and theconductor are preferably removable from the main receptacle tofacilitate cleansing when necessary, and when in place said partitionseparates the waste-chamber 8 from the filtering-chamber 9,` which ispreferabl)7 provided with a filtering material, such as charcoal,tripoli-stone, gravel, or the like. Communicating with the center of theinverted conical bottom of the waste-chamber is a waste-pipe 10, whichis arranged in alignment with the conductor which leads to thewaste-chamber, and communicating with the filteringchamber near its topis an overflow or supply pipe 1l.V A valve-seat l2 is formed in thebottom of the waste-chamber around the inner end of the waste-pipe, andarranged above said seat, -in position to be depressed and brought incontact therewith to close the waste-pipe, is a ball-valve 13. Thisvalveis supported by means of a stem 14, which extends up through theconductorinto a receiving-chamber 15,which is preferably cylindrical inconstruction and is supported upon the cover of the main receptacle, thebottom of said receiving-chamber having an opening 16 and a dependinglip 17, which fits within the opening in the cover of the mainreceptacle, and hence communicates with the axial conductor. Said stemextends through and is attached permanently to the bottom of avertically-movable bucket 18, which is disposed axially in thereceivingchamber and is adapted to receive water through the inletpipe19, which communicates with an opening 2O in the cover or top 2l of thereceivingchamber. A spider 22 is arranged upon the floor of thereceiving-chamber below the bottom of the bucket tov form a bearing forthe lower end of a coiled spring 23, which is arranged at its upper endin contact with the bottom of said bucket to hold the bucket in itselevated position when empty. In order to prevent leaves and trash frompassing int-o the bucket with the waterintroduced through theinlet-pipe,l I arrange a perforated upwardly-convexed shield 24 in thereceivingchamber over the top of said bucket, said shield being providedwith diametrically-opposite depending arms 25, which fit in sockets 26on the inner surfaces of the sides of the receiving-chamber. `The upperend of the valve-stem projects through a guide-opening 27 at the centerof the perforated shield to IOO insure the proper longitudinal movementof the stem and the bucket. Communicating at its inner end with theinterior of the bucket near its bottom and having its other end arrangedoutside of and below the plane ot' the bottom of the bucket is a siphon2S to draw the water from the interior of the bucket after the cessationof the supply through the inlet-pipe to relieve said bucket of weightand thus allow it to be elevated by means of its actuating-spring.

This being the construction o f the improved filter, the operationthereof is as follows: The valve which controls the waste-pipe isnormally held elevated or unseated by means of the actuatingspring ofthe bucket, whereby free access is given to the interior of thefiltering-chamber to ventilate and dry the filtering material containedtherein. WVhen water is supplied to the filter by rain or otherwise,

'it passes first into the bucket and by filling the latter causes it todescend and thereby depress the valve until seated, after which thewater passes down through the receivingchamber, carrying with it leavesand other foreign material, and thence through the conductor to thewastechamber at the bottom of the main receptacle. From this point thewaterascends through the filtering-chamber after passing through theperforations in the conical partition and escapes through the overliowor supply pipe. When the supply of water ceases, the water which iscontained in the bucket is drawn off by the Siphon, and the bucket, withthe attached valve, ascends, thus opening the waste-pipe to allow theleaves and other trash which have accumulated in the waste-chamber toescape. As soon as the valve is seated the water which remains in thefiltering chamber fiows downwardly to and through the waste-chamber,thus cleansing the filtering material and Hushing the waste-chamber tocarry out any foreign material which may be contained therein.

In practice various changes in the form, proportion, and the minordetails of construc tion may be resorted to without departing from thespirit or sacrificing any of Athe advantages of this invention.

Having described my invention, I clairnl.A A filter having a lteringchamber provided with an overflowor supply pipe, asubjacent wastechamber provided with an inverted conical bottom, and a central wasteoutlet and separated from the filtering chamber by a perforatedpartition, a receiving chamber arranged above the filtering chamber, aconductor extending vertically from the bottom of the receiving chamberthrough the filtering chamber to the waste chamber and arranged inalignment with said waste outlet, a spring-supported bucket arrangedconcentrically in the receiving chamber, a valve arranged in the wastechamber in operative relation with a seat contiguous to the Waste outletand having its stem connected to said bucket and extending through theconvided nearits top with an overiiow or supply pipe, and having aninverted conical bottom provided with a waste outlet and a removable topprovided with a central opening, a conical perforated partition arrangednear the bottom of the main receptacle to form a subjacent waste chamberin communication with the waste outlet and a superjacent filteringchamber adapted for the reception of filtert ing material, ya conductorarranged axiallyin the filtering chamber and communicating Iwith thespace below the perforated partition, a receiving chamber seated uponthe `cover of the main receptacle and provided with a central openinghaving a depending lip which extends into the upper end of theconductor, a spider arranged upon the floor of the receiving chamber, abucket arranged concentrically in the receiving chamber, a

valve disposed in operative relation with a valve seat, surrounding thewaste outlet and having its stem attached to the bottom of the bucket,an inlet pipe communicating with the top of the chamber, an upwardlyconvexed perforated shield arranged to cover the bucket and providedwith arms fitting in sockets on the sides of the receiving chamber, theupper extremity of the valve stem being fitted in a guide opening in thecenter of the perforated shield, a spring seated at its lower end on.said spider-'and bearing against the bottom of the bucket, and a siphoncommunicating with the interior of the bucket to withdraw the contentstherefrom after the cessation of the supply, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
